What is RAM? It’s working principles

The operating system resides in a special piece of hardware called RAM. In addition to the operating system, the RAM also contains other application programs. RAM is very important for your computer system because it is its main memory. In this article, we will take a closer look at RAM and explain its main functions.

What are the functions of RAM?

RAM is known for its instability. The data that is present in this memory is stored until you turn off the computer. Its purpose is immediate operation, which unfortunately is short-lived and has a limited number of factors.

Once its memory overflows it starts to update with new components at which point it accesses the hard disk but all this action reduces the speed of the computer.

How does the RAM work?

RAM has a random access function that allows you to access any memory address. Originally the phrase “RAM” was used as a distinction between main memory and standalone memory. The main difference between them is that RAM allows you to save and retrieve data in any order, while in standalone memory you have to do it successively.

The principle resembles a collection of fields, each with its own address, which is determined by counting the bars and lines. If you want to find a particular grid cell, you send the URL of that grid cell via an electrical line.

The RAM is small in size and located in microchips. Accordingly, with the size, the amount of information it can store is also small. The average PC RAM is only 8 GB.

Larger RAM significantly reduces the time that the processor has to read information from the hard disk, and this process takes more time than the same action but in RAM. The time to access RAM is denoted in nanoseconds, and the time to access storage memory is expressed in milliseconds.

How much RAM do you need?

This is a question that only you can answer because it all depends on the purpose for which you are using the PC.

There are two types of RAM:

-Dynamic random access memory

DRAM is the RAM of a typical computational unit, where each bar does or does not have a load in an electrical capacitor. They have to be regularly updated to offset leaks from the capacitor.

-Static RAM

It has no need to be permanently updated, there is a transistor in place of the capacitor, which acts as a trigger. The result is that SRAM is much larger and more costly than the equal amount of DRAM. But at the same time, SRAM consumes less power and runs faster.
